|   | (iv) | Major Maintenance Program Revision: If the Lessee adopts a Major Maintenance Program Revision, either Lessor or Lessee may notify the other that it believes adjustment is necessary
to maintain the Supplemental Rent at levels which accurately reflect the costs associated with obtaining relevant maintenance services (at Lessee’s prevailing costs for the most recent twenty-four (24) months escalated to the relevant rate of
determination at the rate specified for the Annual Supplemental Rent Adjustment). In such event, Lessor and Lessee shall mutually agree upon the amount of any adjustment to the rate otherwise specified herein to reflect such costs associated with
obtaining the relevant maintenance services. Should Lessor and Lessee fail to agree upon the amount of any adjustment to the rate, the matter shall be referred to the Manufacturer, whose decision in the matter shall be binding on the parties. Upon
agreement of Lessor and Lessee or the decision of the Manufacturer, as the case may be, Lessor shall thereupon give notice to Lessee specifying the revised Supplemental Rent rates and the effective date of such revision and Lessee and Lessor shall
be bound by it.  |
